Influence of Ladle Exchange on Inclusions in Transition Slabs of Continuous Casting for Automotive Exposed Panel Steel
نویسندگان
چکیده
In the present work, inclusion analyses were carried out for inclusions in tundish samples and 28 m transition slabs produced during ladle exchange of heats A B. At beginning heat B steel casting, 12th meter casting was position mold meniscus. The number densities containing TiN Al2O3+TiN increased significantly from to 22nd meter, while Al2O3 markedly 13th 20th meter. Therefore, length whose cleanliness seriously reduced about 10 starting casting. It deduced that contamination could be caused by liquid exposure tundish, inflow filling sand next heat, or entrainment flux due fluctuation level at

The Influence of Hematite on High Speed Continuous Casting of Steel Lubricating Powders: Viscosity and Crystallization
Mold powders used in the continuous casting of steel contain the harmful CaF2 as a main substance developing toxic gases such as SiF4 and HF at elevated temperatures. In this study, three samples of I1, I2 and I3, which contained gypsum free Portland cement clinker with different percentages of Fe2O3 (5.68, 6.83, 8.02 ...
متن کاملModeling of Steel Grade Transition in Continuous Slab Casting Processes
Mathematical models have been developed and applied to investigate the composition distributions that arise during steel grade changes in the continuous slab casting processes. Three-dimensional turbulent flow and transient mixing phenomena in the mold and the strand were calculated under conditions corresponding to a sudden change in grade. The composition distribution in the final slab was th...
متن کاملContinuous Casting of Steel
Continuous casting is used to solidify most of the 750 million tons of steel produced in the world every year. Like most commercial processes, continuous casting involves many complex interacting phenomena. Most previous advances have been based on empirical knowledge gained from experimentation with the process. To further optimize the design and improve the continuous casting process, mathema...
متن کاملMathematical Modeling of Heat Transfer for Steel Continuous Casting Process
Heat transfer mechanisms and the solidification process are simulated for a continuous casting machine and the geometric shape of the liquid pool is predicted considering different conditions. A heat transfer and solidification model is described for the continuous casting of steel slabs. The model has been established on the basis of the technical conditions of the slab caster in the con...
